GeoScope 2100 Compact Parametric SBP

GeoScope 2100 Compact Parametric SBP

110 kHz parametric SBP · one housing

  • Deep penetration from a small head — Parametric generation gives up to 30 m penetration from a compact transducer, with high-frequency bathymetry and low-frequency profiling in one unit.
  • One housing, no electronics bottle — 7.5 kg in water and ≤100 W average power: the vehicle gives up little payload, power or volume.
  • Narrow beam, no side lobes — A ~4.5° × 4.5° primary beam rejects off-axis clutter from trenches and slopes, for ≤0.05 m range resolution.
  • Two depth ratings, one design — 300 m for USV mounting, 2,000 m for AUV / ROV integration; built-in bottom tracking, gain compensation and filtering, digital Ethernet output.

GeoScope 2100 is a compact parametric sub-bottom profiler with transducer and processing electronics in a single housing, offered in 300 m and 2,000 m depth ratings. Built on nonlinear acoustics, it transmits at a 110 kHz primary frequency and generates 5 – 25 kHz secondary frequencies in the water — low-frequency penetration without a low-frequency-sized transducer.

There is no separate electronics bottle to mount or cable. The unit delivers up to 30 m of sediment penetration and ≤0.05 m range resolution at 7.5 kg in water and ≤100 W average power — a size, weight and power (SWaP) profile that fits USVs and small to mid-size AUVs and ROVs where payload space and buoyancy trim are tight. Typical work: buried-target search and fine sub-bottom structure.
